농업가뭄 특성 분석 및 대응 전략 연구 = Analysis of Characteristics of Agricultural Drought and Study of Response Strategies

다국어 초록 (Multilingual Abstract)

The increased frequency of natural disasters has been attributed to abnormal climate conditions, with droughts notably causing significant damage. In particular, droughts directly impact the agricultural sector. In recent years, the scale and frequency of damages caused by droughts in South Korea have increased. In 2018, a drought occurred during the crucial panicle formation stage of rice (July－August) due to below-average rainfall and heat waves. This led to a decrease in both the reservoir storage rate and soil moisture. The reservoir storage rate exhibited a decline from July to August, with approximately 300 reservoirs representing less than 50% of the average annual storage rate. This manifested in a two-phase curve which showed increases and decreases in June and August. Based on the rainfall in July, 107 regions experienced drought frequencies typically occurring once every 200 years or more. This resulted in damages such as dry rice paddies (2,153 ha) and withering field crops (20,254 ha). The Korea Rural Community Corporation minimized drought damage by promoting the smooth management of agricultural water supply through the installation of pumped storage reservoirs and direct input of maintenance costs. A comprehensive analysis of the 2018 drought reveals that agricultural water management is not standardized based on factors such as crop type, cultivation timing, and cultivation scale.
Consequently, there is a demand for ongoing water management and the formulation of region-specific drought management measures.
